Sound Barrier Concrete Walls

Noise wall solutions using softsound and sierra wall technologies combine the unmatched strength and durability of precast concrete with a variety of finishes to provide a number features.

Sound barrier concrete walls.

This new technology provides many more benefits including mobility. Determining sound transmission class stc for concrete masonry. While reflective products like concrete have been the traditional material for noise barrier walls the advanced absorptive materials found in our sound barriers present a much more effective noise abatement option. Deadening those vibrations is best done with heavy dense materials that stop noise in its tracks.

Reflective products like block and concrete will only bounce sound waves in various directions. Precast concrete sound walls reduce the perceived noise by as much as half while absorptive treatments have been found to further reduce noise pollution. Concrete is a heavy material that poses numerous challenges while absorptive noise barrier walls are made with durable lightweight metals and non corroding materials. The easiest strategy is to add a second layer of drywall to build up a thick sound deadening barrier.

The wood based material is lightweight averaging just 36 40 pounds per cubic foot. Versatile noise wall solutions using precast concrete. Newer wall systems are lighter easy to customize and work for a variety of applications. With color additives or stains and textured form liners a precast wall can blend in with a city s architecture and local topography or stand out by capturing community s theme or identity.

Which is something that concrete walls could never offer. The sound waves hit the wall and the reflective surface of the concrete causes the sound wave to go in the opposite direction. Excessive noise contributes to numerous health problems. Durable under all weather conditions our concrete sound walls are resistant to mildew insect nesting rotting termites and more.

What makes our outdoor sound barriers so attractive is they serve as a protective security fence attractive privacy wall versatile sight barrier and as an economic retaining wall. Sound transmission class stc provides an estimate of the acoustic performance of a wall in certain common airborne sound insulation applications the stc of a wall is determined by comparing sound transmission loss stl values at various frequencies to a standard contour stl is the decrease or attenuation in sound energy in db.

As clearly defined by the federal highway administration a noise barrier can achieve a 5 db noise level reduction when it is tall enough to break the line of sight from the highway to the receiver such as a home or person.

Reflective walls of solid concrete that create a barrier and push sound away from homes or other areas being shielded. Newer research proves concrete sound barrier walls are some of the worst offenders for creating unwanted and unpredictable reflected noise issues. While both the federal and state governments have made efforts to address the issue of highway noise and its adverse impacts on society their traditional remedy has been to place large sound reflective concrete barriers on the worst offenders. When it comes to heavy brick and stone are great but impractical for retrofitting your interior walls.
